Abstract

A novel type multi-sectional detector consisting of separate sections has been developed. Signals from each section pass through a shaping amplifier channel and then are mixed in a special manner. This principle allows reduction of detector’s and amplifier’s electrical noise in many times, and due to this allows one to develop detectors and spectrometers for various types of radiation with characteristics unreachable at present using traditional methods. For example, it is supposed to obtain energy resolution for alpha-particles 30 keV with active area of the detector 40 cm2. It is possible to create semiconductor spectrometers and radiometers with high resolution and the area of detectors of hundreds of cm2. Possibilities and limitations of this principle had been examined and a series of multi-element detectors and an alpha-spectrometer based on them has been developed.
